- Added experimental util.parseArgs helper and ESM loader hooks API with chaining support, expanding command‑line and module loading capabilities.
- Enhanced the Web Crypto API by adding CFRG curves (Ed25519, Ed448, X25519, X448) and removing Node‑specific extensions, aligning with other runtimes.
- Introduced numerous minor APIs (custom events, abort‑signal propagation, DNS promise constants, read options, HTTP diagnostics, etc.) and marked several deprecated features in docs.
